ing had therein to the accompanying drawing. I

The present invention has reference to compasses.

The compass in accordance with this invention is characterized by the fact that the magnetic needle and the adjustable direction indicator are coated with luminous paint which is visible in the dark. Besides the bottom plate is coated with luminous paint and a graduated plate arranged above the same is suitably cut out to represent the cardinal points of the compass, so that the same will also be visible in the dark.

In Figure 1 of the accompanying drawing which represents the compass in plan, the luminous parts are indicated in black. Fig. 2 represents a section on the line AB of Fig. 1 with parts shown in elevation.

The magnetic needle 0 is suspended ip a known manner on a pin b fixed in the Hottom of the casing, and is provided likewise in a known manner, with an arm 0 to engage the hub of the needle and adapted to be actuated from the outside; this arm serves for lifting the needle oil' its pivot when it is not in use.

The graduated plate 01 is arranged on the bottom of the compass case; it is provided with the letters N, E, S, W indicating the cardinal points and also with the lines or dots marking the intermediate points. The fixed bottom plate f beneath the graduated plate (1' is coated with luminous paint so that the letters and marks cut out of the graduated plate appear in luminous paint. Below the fixed bottom plate f a rotatable bottom plate hprovided with a milled edge is arranged to -Jc on this plate h the pin b carrying the on the graduated plate. The plate f, carrying the luminous paint, can be made loosemateriai whether it revolves With the bottom or not. Both the direction indicator mandi the magnetic needle 0 are coated on their coated in order to distinguish it.

. v The device has mainlyfor its object to or travel at night. I am aware that in devices of this kind it elements wit luminous aint but my invention is characterized b arrangement whereby the'ma netic needle, the steering needle and the etters distin guishing the cardinal points appear more distinctiy with a luminous paint efi'ect.

Having now particularly described and ascertained the nature of my said invention I declare that what I claim is:

In a compass in combination a magneticncedle, a center pin secured in a revoluble bottom, an adjustable direction indicator tom, a disk on said bottom provided with luminous paint and a graduated plate above marks punched out of the same substantially as described.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.
